Reproductive robustness differs between generalist and specialist maternal rabbit lines: the role of acquisition and allocation of resources [0.03%]
兔妈妈一般氏族和专业氏族的繁殖适应力存在差异性：资源获得与分配的作用
Davi Savietto,Nicolas C Friggens,Juan José Pascual
Davi Savietto
Background: Farm animals are normally selected under highly controlled, non-limiting conditions to favour the expression of their genetic potential. Selection strategies can also focus on a single trait to favour the most...
Strategic test-day recording regimes to estimate lactation yield in tropical dairy animals [0.03%]
用于估计热带奶牛品种泌乳量的战略性测试日记录制度
David M McGill,Peter C Thomson,Herman A Mulder et al.
David M McGill et al.
Background: In developing dairy sectors, genetic improvement programs have limited resources and recording of herds is minimal. This study evaluated different methods to estimate lactation yield and sampling schedules wit...

Standard error of the genetic correlation: how much data do we need to estimate a purebred-crossbred genetic correlation? [0.03%]
纯种与杂交品种遗传相关性的标准误差：我们需要多少数据来估计纯种与杂交品种的遗传相关性？
Piter Bijma,John W M Bastiaansen
Piter Bijma
Background: The additive genetic correlation (rg) is a key parameter in livestock genetic improvement. The standard error (SE) of an estimate of rg, r^g, depends on whether both traits are recorded on the same individual ...
Variance components for susceptibility to Mycobacterium bovis infection in dairy and beef cattle [0.03%]
牛结核分枝杆菌感染的易感性在奶牛和肉牛中的方差组份分析
Ian W Richardson,Dan G Bradley,Isabella M Higgins et al.
Ian W Richardson et al.
Background: Infection of livestock with bovine tuberculosis (bTB; Mycobacterium bovis) is of major economical concern in many countries; approximately 15 000 to 20 000 cattle are infected per year in Ireland. The objectiv...
Identification of genomic regions associated with inbreeding depression in Holstein and Jersey dairy cattle [0.03%]
在荷斯坦和 jerseys 奶牛中鉴定与近交衰退相关的基因组区域
Jennie E Pryce,Mekonnen Haile-Mariam,Michael E Goddard et al.
Jennie E Pryce et al.
Background: Inbreeding reduces the fitness of individuals by increasing the frequency of homozygous deleterious recessive alleles. Some insight into the genetic architecture of fitness, and other complex traits, can be ga...
Protein evolution of Toll-like receptors 4, 5 and 7 within Galloanserae birds [0.03%]
禽类 toll 样受体 4、5 和 7 的蛋白质进化研究
Michal Vinkler,Hana Bainová,Josef Bryja
Michal Vinkler
Background: Toll-like receptors (TLR) are essential activators of the innate part of the vertebrate immune system. In this study, we analysed the interspecific variability of three TLR (bacterial-sensing TLR4 and TLR5 and...
Sexually dimorphic genetic architecture of complex traits in a large-scale F2 cross in pigs [0.03%]
猪大规模F2杂交群复杂性状的性别分型遗传结构
Leilei Cui,Junjie Zhang,Junwu Ma et al.
Leilei Cui et al.
Background: It is common for humans and model organisms to exhibit sexual dimorphism in a variety of complex traits. However, this phenomenon has rarely been explored in pigs. ...
Genomic prediction based on data from three layer lines using non-linear regression models [0.03%]
基于三个蛋鸡品系数据的基因组预测研究（非线性回归模型）
Heyun Huang,Jack J Windig,Addie Vereijken et al.
Heyun Huang et al.
Background: Most studies on genomic prediction with reference populations that include multiple lines or breeds have used linear models. Data heterogeneity due to using multiple populations may conflict with model assumpt...

A comparison of principal component regression and genomic REML for genomic prediction across populations [0.03%]
比较主成分回归和基因组REML进行跨群体的基因组预测能力
Christos Dadousis,Roel F Veerkamp,Bjørg Heringstad et al.
Christos Dadousis et al.
Background: Genomic prediction faces two main statistical problems: multicollinearity and n ≪ p (many fewer observations than predictor variables). Principal component (PC) analysis is a multivariate statistical method t...

利用大白猪与民猪杂交群体开展骨骼长度的全基因组关联分析研究
Long-Chao Zhang,Na Li,Xin Liu et al.
Long-Chao Zhang et al.
Background: In pig, limb bone length influences ham yield and body height to a great extent and has important economic implications for pig industry. In this study, an intercross population was constructed between the ind...
